71058 Software Sellers

I am currently the owner of WWW.SoftwareSellers.net. I just recently purchased this member site and I am looking for some ease of administration. I currently have a script installed by www.illmatic.net. This allows a new member to sign up and he is given a username and password. When they go to the member part of the site it ask for the username a password before they can go to that page. Once they get there they download software from a link provided in HTML. This is very taxing and it is hard for me to constantly keep adding new software. I would like some kind of console with a database that would allow me to add my software give a description and images then create an addition to my pages in my member section. I am a little new at the member website concept so any suggestions to make this site alot more easier to manage and more attactive to new members would certainly be helpful. I just need a price and a time frame so I can get the ball rolling. Thanks, Jack
